FIELD OF THE INVENTION

The present invention relates generally to baby products and nurseryaccessories. More particularly, embodiments include a weight scaleincorporated into a diaper changing and cleaning pad. for babies andyoung children. More particularly embodiments include an electronicweight scale capable of wireless communication incorporated into adiaper changing and cleaning pad for babies and young children.

DESCRIPTION OF THE RELATED ART

There a many different blankets, changing pads, and cleaning pads on themarket to protect furniture and floors from diaper contents and to keepa baby from rolling off of the changing surface and hurting himself orherself. A changing pad is typically an elongated, soft cushion coveredin a water resistant or waterproof material so that a baby has acomfortable place to safely rest while a parent removes a baby's diaper,cleans the baby, and applies a fresh diaper. Many changing pads haveelevated edges along the long sides to keep a baby from rolling off thepad and getting hurt. Changing pads frequently include a safety belt,vest-like restraint, or swaddle restraint to further reduce the chancesof a baby rolling or falling off of the changing pad.

Many changing tables, changing dressers, and other pieces of nurseryfurniture include a standard-dimension raised frame built to securelyhold a changing pad on the furniture piece's top surface. Changing padsalso often include slip-resistant feet and a leash of material that canbe anchored to a dresser, changing table, or other piece of furniturewith a nail, tack, or snap. The changing pad leash, the slip-resistantfeet, and the nursery furniture frame are intended to secure the babychanging pad so the pad will not tip off of the furniture as a babyadjusts position. In other circumstances changing pad have beenspecifically designed to stably rest on or latch on to the top of a cribor car seat.

In addition to changing pads, changing pad covers are a popularaccessory. Changing pads are typically covered in vinyl which is easy toclean but can be cold and clammy to the touch, making a. babyuncomfortable during an already intrusive cleaning process. Changing padcovers are typically plush or fabric covers that stretch over a changingpad and are secured by elastic tension or some other mechanism. Changingpad covers are removable and often machine washable, and they add alayer of cushion, comfort, and warmth for a baby. Changing pad coversare especially recommended during night-time diaper changes in colderclimates so that the cold surface will not completely wake up ahalf-asleep baby.

In a crowded nursery, every horizontal surface becomes valuable storagespace and every item must deserve its spot. All changing pads occupyspace, but none serve any purpose beyond providing a cleanable surfacefor diaper changing and baby cleaning. None provide or record anyinformation about the baby or the changing process. In general, changingpads have not changed since the 1920s adoption of vinyl polymers.

In order to address the above-described exemplary problems, and othersimilar problems, a novel smart diaper changing pad is needed to providea parent with information regarding a baby's health and growth.

DETAILED DESCRIPTION

Various embodiments disclosed herein relate to a smart diaper changingpad 100 incorporating an electronic scale. The electronic scale elementcan be incorporated into any shape or type of changing pad 100,including traditional foam or batting changing pads, memory foamchanging pads, organic changing pads, and even portable or foldablechanging pads. The electronic scale elements can be integral to thechanging pad 100 or may be incorporated into a separate platform 105placed beneath a changing pad. The electronic scale may return weightinformation visibly, as through a display, through wirelesscommunication to a separate computing device 10 (as shown in FIG. 15),or both. The electronic scale can be as sensitive as technology allowsand may use multiple strain gauges or load cells 125 to increasesensitivity and effective measurement range.

In the following detailed description, numerous specific details are setforth in order to provide a thorough understanding of the invention.However, the invention may be practiced without these specific detailsor in any combination incorporating multiple versions of these detailstogether. In other instances, well known methods, procedures, and/orcomponents have not been described in detail so as not to unnecessarilyobscure aspects of the invention.

With respect to FIGS. 1-14, in a first embodiment, a smart diaperchanging pad 100 includes a central depression 101 with two elevatededges or sidewalls 102, one on each side. To minimize the absorption ofundesirable odors or germs, the outer surface may be comprised of awaterproof or water resistant material such as, but not limited to,vinyl, silicon, nylon, polyester, plastic, leather, treated fabrics orantibacterial materials. The central depression 101 and the elevatedwalls 102 may be padded so as to be comfortable for a baby and to avoidinjury. The interior cushion 106 can be made of any material, includingbut not limited to, batting, down, cotton, foam, micro-cell foam, memoryfoam, stuffing, air-filled pockets, or liquid-filled pockets. In oneembodiment, the two elevated edges 102 angle up from the centraldepression 101 and in some embodiments reach a height (h) of three tofive (3-5) inches to keep the baby from rolling either direction off ofthe smart diaper changing pad 100. In one embodiment, the weighingdevice is between thirty (30) and thirty-six (36) inches long Wandbetween twelve (12) and eighteen (18) inches wide (w). In otherembodiments, the edges 102 curve up instead of angling up, and theheight of the walls 102 may vary in different devices. The smart diaperchanging pad 100 may be constructed with different dimensions withoutdeparting from the present invention.

In another embodiment, one variation of which is discussed in greaterdetail with respect to FIG. 14, the outer surface may instead besupported on a rigid platform 105 or stretched over a wood or metalframe. If the outer surface is suspended over a frame, the centraldepression 101 is suspended (like a hammock) instead of filled withpadding. If there is a hard frame or platform 105, the elements of theframe within reach of a baby should be padded or cushioned 106 beneaththe outer material.

As disclosed in FIGS. 6, 7, 8, and 12, in some embodiments, the changingpad 100 includes slip-resistant feet 104. The force or mass sensors 125may be connected to the legs, feet, or pads 104. In some embodimentswith flexible central depression cushion 106, the smart diaper changingpad 100 may require that a rigid element or platform 105 be includednear the bottom of the device and the feet 104 are connected directly tothe rigid platform 105 so that the flexibility of the softer materialsdoes not negatively impact the sensors' 125 ability to accuratelymeasure mass or force. The feet 104 are attached beneath the rigidplatform 105, and the sensor elements 125 associated with each foot 104may be hidden inside of the outer material of the smart diaper changingpad 100. Additionally the legs or supports 104 for the sensors 125should be configured to create a stable and slip-free surface for thesmart diaper changing pad 100 to avoid injury. As shown in the FIGS., 4feet 104 are shown, but more or fewer feet may be incorporated withoutdeparting from the present invention. A sensor 125 should be associatedwith each foot or point contacting the underlying substrate, but asingle sensor 125 could be connected to multiple feet.

In some embodiments, the non-electronic elements of the smart diaperchanging pad 100 can be made of organic materials. In these embodiments,the electronic materials can be fully enclosed on the bottom-side of thedevice to avoid any exposure to the baby. Alternatively the electronic(and other inorganic) elements can be entirely contained in a separateplatform that is fully separable from the fully organic baby-supportingelements. In some embodiments, the separate platform comprising theinorganic elements may be the same as the rigid platform 105 and theorganic elements may comprise the cushioned elements 106. The platformmay be specially designed to pair with the organic baby-supportingelements.

The electrical components in the smart diaper changing pad 100 includeat least a mass or force sensor element 125 and an indicator element(e.g., the display 103 or a feedback element 128). The pad 100 may alsoinclude other electronic components such as a processor 122, an externalcommunication system 124, a power supply 121, a memory 123, user inputcontrols 126, and other sensors 125 to measure other information aboutthe user or environment.

The mass or force sensor element 125 may detect either force or mass.The downward force of an object is equal to the mass of the objectmultiplied by the local gravitational field (on the earth's surface,approximately 9.81 meters per second squared). Traditional sensorelements 125 used for detecting either mass or force include straingauges or load cells 125. Other sensors may also or instead be included.When a force is applied to a material, that material elongates orcontracts, which adjusts the electrical parameters across the material.A strain gauge is a transducer that detects that change in electricalparameters (typically either resistance or resistivity) in response toan applied force. Load cells are typically configurations of straingauges in some sort of bridge configuration, which allows an electronicestimate of the force. One of the most common sensor configurations is aWheatstone bridge (including half or quarter Wheatstone bridges). Anelectronic scale may incorporate one or more sensor elements 125. Agreater number of sensor elements 125 can increase the effective sensorrange and increase the sensitivity within that range. In some cases, theconfiguration of multiple strain gauges 125 also allows the scale topassively correct for humidity- or temperature-based interference.

With a mass or force sensor 125 incorporated into a diaper changing pad100, the smart diaper changing pad 100 can passively record a baby'smass or weight each time that the baby's diaper is changed. Depending onage, a baby's diaper may need to be changed as often as a dozen timesper day, which provides a number of data points. Parents often ownmultiple changing pads (especially in multi-story homes), but evenparents in modest homes often own a mobile changing pad in addition to anursery or living room changing pad 100. The mass or force sensor 125can be incorporated into both stationary and mobile changing pads 100.Multiple smart diaper changing pads 100 could collectively create acomprehensive diaper changing record.

An indicator element allows a user to learn the results of themeasurement and may include a display 103, and/or some other sort ofvisual, auditory, or haptic indicator 128. Common auditory indicatorsinclude speakers and buzzers. A speaker may declare the baby's weight orthe speaker may simply play comforting tones for the baby during thechanging process. The tones could be stored in the smart diaper changingpad 100 or played from a user's mobile computing device 10 or cloudmusic service. Common haptic indicators convey information throughvibration. A haptic indicator might vibrate in a set pattern to tell aparent when a measurement is complete or when any other message isintended for the parent. Alternatively, a haptic indicator could producea comforting vibration or massage feeling to help relax a baby during adiaper change. Common displays include projectors, LCD (liquid crystaldisplays) and LED (light-emitting diode) displays. The display 103 canbe dimmable so that it will not cast too much light or wake a baby in adarkened room.

As demonstrated by the three different display 103 locations in FIGS. 1,9, and 11, the display 103 can be located or oriented anywhere on thesmart diaper changing pad 100. Because the pad 100 is primarily used bya parent standing alongside the long side of the smart diaper changingpad 100 (to the baby's right or left), it may be preferable in someembodiments to arrange the display 103 in such a way that theinformation on the display 103 appears right-side up for a user standingalongside the long side of the smart diaper changing pad 100. Thedisplay 103 can be set on the central depression 101 or on the elevatedsidewalk 102. In one embodiment, the display can be rotated 90 degreesto be legible for user's standing either alongside the long side of thesmart diaper changing pad 100 or at the base of the smart diaperchanging pad 100. This rotation may be a mechanical movement or thedisplay may simply rotate the orientation of the elements on the display103.

In a series of alternate embodiments not shown in the FIGS., theelevated edge 102 surrounds the central depression 101 on all sides,either with four orthogonal sides 102 or with an ovular or figure-eightsidewall 102 surrounding the entire pad 100. In another embodiment, thesidewall 102 is generally U-shaped with one open end where the baby'slegs will be located. Still other embodiments include a curved centraldepression 101 to keep a baby in place in the center of the smart diaperchanging pad 100 during a diaper change. In some embodiments, theportion of the smart diaper changing pad 100 that will support a baby'shead may be elevated from the portion of the smart diaper changing pad100 that will hold the baby's legs with the entire central depression101 angled down from head-side to leg-side.

In some embodiments, a leash (not shown) of material that can beanchored to a dresser, changing table, or other piece of furniture witha nail, tack, or snap (not shown). The changing pad leash, along withthe slip-resistant feet 104 and the nursery furniture frame are intendedto secure the baby changing pad 100 so it will not tip off of thefurniture as a baby adjusts position. In some embodiments, the changingpad 100 includes a safety belt, vest-like restraint, or swaddlerestraint (not shown) to further reduce the chance of a baby rolling orfalling off of the changing pad 100.

In other embodiments (not shown), the smart diaper changing pad 100 maybe foldable so that it can be made portable or more easily stored. Thesmart diaper changing pad 100 may fold multiple times, so long as theforce or mass sensors are the only things bearing any baby weight duringmeasurements.

In still other embodiments (not shown), the smart diaper changing pad100 will include pockets (not shown) to store items such as cleandiapers or wipes or hooks or loops (not shown) so that the smart diaperchanging pad 100 can hang from a stroller or shoulder. Alternatively thesmart diaper changing pad 100 could include hooks (not shown) thatattach a garbage bag so that parents have somewhere to store theirdirties.

Additionally in some embodiments, the display 103 can be entirelydisconnected from the smart diaper changing pad 100 and continue todisplay information from the smart diaper changing pad 100. The displaycould be placed or mounted somewhere convenient for the parent to lookduring a diaper change or feeding, and the display could communicatewirelessly with the smart diaper changing pad 100. In some embodiments,the removable display would include a touchscreen 103, buttons 126, orsome other user feedback element that can control the smart diaperchanging pad 100 wirelessly. In some embodiments, the display mayinclude its own secondary battery 121 or could be mounted somewhere thatprovides an external power source 121 for the display. The secondarybattery 121 could charge from the power in or running through the smartdiaper changing pad 100 whenever the display is docked with the smartdiaper changing pad 100.

One or more external communication systems 124 may be incorporated intothe smart changing pad, including both wired and wireless communication.A wired communication system 124 (including Ethernet, USB, USB type C,and many others), is the most simple, but not always the most desirable.In some embodiments, cables may be undesirable, presenting a potentialhazard for young children, making wireless communication preferable. Insome embodiments, the smart diaper changing pad 100 may comprise awireless communication module 124, which encompasses all of the elementsnecessary or desirable to communicate over one or more specific wirelessprotocols. The smart diaper changing pad 100 may incorporate one or morewireless communication protocols, including cellular network (including2G, 3G, 4G, and LTE), GSM, CDMA, AMPS, EDGE, HSDPA, UMTS, WLAN/Wi-Fi(IEEE 802.11), WiMAX, Bluetooth (IEEE 802.15), BLE (Bluetooth lowenergy), ZigBee (IEEE 802.15.4), wireless USB/ultrawideband, wBAN(802.15.6), infrared, NFC, or any type of proprietary communicationmethods. These are a few of the known wireless protocols available forincorporation in a smart device, but others may be used or includedwithout departing from the present invention.

The smart diaper changing pad 100 (or any electronic peripheral) cancommunicate directly with another device (e.g., Bluetooth communicationbetween the smart diaper changing pad 100 and a mobile phone 10) ordirectly with an external cloud or network (such as Wi-Fi access to alocal network which allows external communication to remote datastorage). It may be sufficient to include only one wireless protocol124, but in some other cases it may be desirable or economicallyreasonable to include multiple wireless protocols 124.

In some embodiments, the smart diaper pad 100 may include a processor122 and a memory 123 capable of storing information, both short-term andlong-term, and processing the change in electrical parameters receivedfrom the force or mass sensors 125 to calculate a force or mass. Theprocessor 122 may also convert the information into familiar units suchas newtons, grams, kilograms, ounces, pounds, stones, or any other unitof force or mass. The processor 122 may also perform other tasks such ascontrol power management, drive and control a display 103, organizeinformation for transmission to a separate computing device 10,determine when to begin or stop measuring or recording, determine whento power on or power off the smart diaper changing pad 100, control howto store and access memory 123, and/or any other processes that thesmart diaper changing pad 100 may need to perform locally. The processor122 may be a single general purpose processor with one or more cores ormay refer to a group of general purpose or specific-purpose processorsworking together. The memory 123 may include both random access memory123 a for running applications or processes and long-term storage memory123b. The memory 123 may be selected from solid state, traditionalmagneto-mechanical, DNA-storage, holographic storage, or any other datastorage technology.

In some embodiments, the smart diaper changing pad 100 will require apower supply 121 to provide an electric bias for any sensors 125, toilluminate or control the display 103 (including, for example, bothdisplaying an image on an LCD and illuminating the LCD with an LED) orfeedback elements 128, to access or record information to and from thememory 123, to power the processor 122 and to generally enable any typeof electronic performance. This power supply 121 may be a cable drawingpower from an outside source such as a wall socket, a USB plug, anexternal battery, or a computer. Alternatively this power supply 121 maybe a chemical battery or any other element capable of locally storingenergy. Because the smart diaper changing pad 100 will be used withbabies and small children, it may be preferable to minimize externalwires for safety. With the goal to minimize risk to children, it may bepreferable to rely on internal batteries for the power supply 121 insome embodiments. These batteries 121 may be rechargeable orreplaceable, and there may even be an energy harvesting device (e.g. asolar cell or an element capable of capturing energy from movement orheat) incorporated within the device. Alternatively wireless chargingmay be used to power the smart diaper changing pad 100 withoutendangering children.

In one embodiment, wireless charging could connect to a piece ofcharging furniture incorporating one or more charging pads. That pieceof furniture may connect to a central power source or wall socket, andmay optionally include a socket cover or socket sheath to avoidendangering children. Each piece of powered nursery equipment could reston top of or couple to one of the wireless charging pads and thereforeobtain external power without adding any potentially hazardous wires tothe nursery.

The wireless charging pads could be configured to only provide powerwhen a recognized device is coupled, so there is no risk ofunintentionally shocking a human or damaging any other electronicdevice. Alternatively the furniture could function as a power extensioncord or hub. Instead of including a wireless charging pad that radiatesenergy, the furniture could have conveniently located sockets fordirect-socket devices that draw power through the charging furniture.The furniture could connect directly to a power and/or data source and aseries of sockets or ports could be built directly into the top or sidesof the furniture. Although it is easy to imagine this arrangement withtraditional wall electric sockets or USB ports, this arrangement couldbe used for any kind of power, data, or power/data connector. Forexample, a dresser or chest could draw power from a wall socket and havea series of electric sockets built into the top of the dresser or chest.The connection to the wall socket could be made in a way to eliminateany choking or swallowing danger from children (e.g., a rigid extensioncouples to the wall socket and potentially screwed directly into thewall socket so it cannot be trivially detached). Additionally asurrounding sheath or manifold could protect the socket from outsideinterference. The direct-socket charging electronic nursery equipmentdesigned for the charging dresser could be designed to eliminate anyexternal wires so that the bottom of the nursery equipment orperipherals has fold-down prongs or fold-down male connectors that plugdirectly from the base of the peripheral into the charging nurseryfurniture.

Instead of traditional wall sockets or USB, this direct-socketconnection could also be a proprietary connector. It may be preferablein some embodiments or with some connectors to have an emptying cavityfrom the bottom of each socket in case any type of :liquid spills in. Inother embodiments, the sockets could have spring-loaded covers that arepressed out of the way by matching prongs to keep a curious or wanderingchild from having an unexpected electric surprise. In some embodiments,it may be preferable to use a lower current power source (e.g., the 5volts available from traditional USB) for nursery equipment because thelower current could pose significantly less risk of electrocution.

In some embodiments, these direct-socket pluggable peripherals couldalso include a battery back-up and run off of battery power wheneverthey are not receiving an external charge. An indicator LED could letyou know if the device is running off of battery or external power. Thedevices could include a low power mode when running off of battery, forexample producing less light or spinning at a lower speed. In someembodiments, users could disable low power mode and burn battery powerfaster if the user thought the improved experience was worth theshortened battery life.

Direct-socket charging electronic nursery equipment could optionally runexclusively off of the direct-socket charging power or they could alsoinclude internal batteries to run when not paired with a direct-socketcharging furniture. Direct-socket charging electronic nursery equipmentcould include breast pumps, baby monitors, nightlights, video cameras,infrared baby monitors, phone-charging docks, moving or musical babytoys, displays, speakers, the above-discussed smart diaper changing pad100, or any other electronic device that may assist a parent with a babyor conveniences a parent while the parent spends time with a baby. Anyof these elements could include additional sensors to improve thebehavior of the individual devices.

In some embodiments, the smart diaper changing pad 100 would includeuser interface or input controls 126 such as a touch screen, buttons,knobs, switches, or voice or gesture recognition activation (due topotentially dirty hands). These user input controls 126 could includecontrolling whether a device is powered on, when to take a measurement,a tare/multitare/untare function, which parent profile is active, whichbaby profile is active, what unit of measurement is displayed, thebrightness of display 103, and whether any peripheral attachments areactivated.

The smart diaper changing pad 100 may include any other sensors 125 thatmay be useful for monitoring your baby's health or development. Thesesensors 125 can monitor any number of bin-variables including—but notlimited to conductivity, capacitance, impedance, muscle percent, fatpercent, hydration, heart rate, body temperature, and glucose levels inaddition to weight measurement.

In another embodiment, the smart diaper changing pad 100 could beconfigured to enable multiple peripheral attachments. These peripheralsmay be non-functional, powered, or even require water pressure, any ofwhich could be enabled through the smart diaper changing pad 100. Theseattachments may be intended to distract and entertain a baby such as amobile or dangling toy or a light, speaker, or display. The attachmentsmay also be intended to make the changing process easier or moreconvenient, such as a water spray nozzle that receives water from aconnection point on the smart diaper changing pad 100 or an infraredlight or heating pad to warm a baby during the changing process. Anywater or power may be routed through the smart diaper changing pad 100to the peripheral. The smart diaper changing pad 100 could be connectedto a water source, which would enable any water-powered orwater-providing peripheral. The smart diaper changing pad 100 couldsimilarly provide electricity to any powered peripheral through aconnection point (e.g., USB plug, wireless power, or proprietaryconnection point). Peripherals could include an attachment for measuringbaby length, speakers, lights, displays, powered toys, water sources,suction devices, blowing devices, warming devices, wipe-warmers,cameras, or additional add-on sensors an IR (infrared) thermometer or aheart-rate monitor).

One specific embodiment of a smart changing pad 100 attachment is adevice for determining baby height, baby length, or baby girth. Thisdimensional measuring device could be as simple as a ruler that ispermanently marked on the device or as complicated as a combination oflight emitters and light detectors (including invisible lightfrequencies) that measures the length that the baby blocks. Anotherembodiment of a dimensional measuring device for the smart changing pad100 would be a measuring tape that anchors to the smart diaper changingpad 100. The smart diaper changing pad 100 could automatically recordthe distance that a measuring tape is unwound either automatically orwhen a user clicks an associated button. Alternatively a parent couldmanually enter the parents dimensions after visually noting the baby'sdimensions against markings on the smart changing pad 100.

In another embodiment, the smart diaper changing pad 100 couldcommunicate, either wirelessly or through optical sensing, with a devicethat the baby is wearing, thereby collecting more information forparents. One example of a useful wearable would be a smart diaper thatcan send a signal when a diaper needs to be changed, such as therecently proposed TweetPee line of diapers from Huggies ®. This signalmay be sent when the diaper notices that certain pockets are saturatedwith liquid or stretching due to excess weight. The time from the diapersignaling the need to be changed until the diaper is actually changedcan be recorded. Parents could use this as one indicator to determine ifa nursery or pre-school is providing adequate or insufficient attentionto a child. Additionally the smart diaper changing pad 100 couldcommunicate even with non-smart diapers. There are a number ofchemically reactive diapers corning out these days, such as the PixieScientific diapers that analyze a baby's waste to determine if a baby isexperiencing any detectable health issues or chemical imbalances. Acamera or sensor 125 attached to the smart diaper changing pad 100 couldanalyze the grid on the Pixie Scientific diapers and record whichcolored boxes were triggered.

Referring now to FIG. 13, in some embodiments, the smart diaper changingpad 100 may be covered with a changing pad cover 107. Changing pads 100frequently include an outer surface made from vinyl, plastic, silicon,or some other water-resistant material that is easy to clean.Unfortunately these materials can be cold and clammy to the touch,making a baby uncomfortable during the cleaning and changing process.Changing pad covers 107 are typically plush or fabric covers thatstretch over a changing pad 100 and are secured by elastic tension orsome other mechanism. In some embodiments, the changing pad cover 107may include a transparent window 108, through which a user can view thedisplay 103 on the changing pad 100.

Referring now to FIG. 14, and as previously described, if there is ahard frame or platform 105, the elements of the frame within reach of ababy should be padded or cushioned 106 beneath the outer material. Insome embodiments, this changing pad cushion 106 may rest on top of thesmart diaper changing pad 100 and cushion the central depression 101 andthe elevated sidewalls 102.

Referring to FIGS. 15-18, separate computing device 10 includes adisplay or touch screen 11 and one or more user interfaces 12. AlthoughFIGS. 15-18 show the smart diaper changing app accessed on a smartphone10, similar information may be accessed through a webpage. In oneembodiment, any information measured, recorded, or entered into thesmart diaper changing pad 100 may be shared with a smart diaper apprunning on a separate computing device 10. Some examples of separatecomputing devices 10 include smartphones such as the Apple® iPhone orthe Samsung Galaxy Note®. As an example, a Bluetooth or Wi-Fi enabledsmart diaper changing pad 100 can communicate directly with a smartdiaper app on a smart phone 10. The smart diaper app on a smartphone ortablet 10 can make a note of all weight recordings or sensor recordingsover time and keeps a comprehensive record of diaper changes. Thisrecord may include measurements taken by multiple devices and evenmeasurements manually entered by a parent or smart diaper app user. Thesmart diaper app may even allow users who do not own a smart diaperchanging pad 100 to manually enter all recordings and to enjoy many ofthe same features as the smart diaper changing pad 100 owners.

FIG. 15 shows an exemplary weight chart screen in the smart diaperchanging app running on a separate computing device 10. The presentscreen of the smart diaper changing app displays a weight chartgenerated either through manual data entry in the smart diaper changingapp or automatically by the smart diaper changing pad. The graph showsvarious curves for statistically significant curves, such as 25^(th)percentile, mean, median, and 75^(th) percentile. The screen alsoidentifies the profile that is charted by name, age, and displays theprofile's current weight and weight percentile. As shown in FIGS. 15-18,in some embodiments, regardless which screen a user is on, the smartdiaper changing app includes one or more quick-access buttons toimmediately open a specific page (in this case, the five quick-accessbuttons point to the profile page, the weight chart, the height chart,the feeding detail page, and the sleep detail page. In anotherembodiment, another quick-access button could be included to access thediaper diary page described more completely with regards to FIG. 17below.

FIG. 16 shows an exemplary profile-at-a-glance screen of the smartdiaper changing app. This screen of the smart diaper changing appdisplays a collection of relevant charts, intended to provide quickaccess to relevant information, including current baby weight with aminiaturized weight chart, current length with a miniaturized lengthchart, and volume of the last feeding with a miniaturized feeding volumechart. All 3 subsections indicate how long it has been since the lastinformation was entered, along the overall profile information,including the name and a photo of the baby associated with the profilealong with the baby's age.

FIG. 17 shows an exemplary diaper diary screen in the smart diaperchanging app, which displays the time and date of the most recentlyrecorded diaper change, how much time has passed since that change, thechanged baby's weight before and after diaper change, the net change inweight attributable to the dirty diaper, and checkboxes indicatingwhether that particular diaper included urine or feces. Turning to FIG.18, an exemplary feeding detail screen displays the time and date of themost recently recorded feeding, how much time has passed since thatfeeding, the changed baby's weight before and after feeding, the netchange in weight attributable to the consumed liquid. In someembodiments, the feeding detail screen would also display an estimate ofthe fluid volume consumed based on a mass to volume conversion estimate.

In one embodiment, the smart diaper changing pad 100 will automaticallytare when it is first turned on. This could be when it detects nearbymotion, when a user input control 126 is activated, or in response toany type of input or observed behavior. In another embodiment there is atare button 126 that a parent can press just before placing the baby onthe smart diaper changing pad 100. A user can also tare (or zero out)the smart diaper changing pad 100 before a diaper is removed tonegatively measure the weight of the dirty diaper or at any other time.

In one embodiment, the smart diaper changing pad 100 will take ameasurement when a baby is first placed on the smart diaper changing pad100, another measurement when the smart diaper changing pad 100determines that the diaper and its contents have been removed from thesmart diaper changing pad 100 (preferably after cleaning, but in someembodiments this could be before cleaning), and a third measurementafter the baby is dressed in a fresh, clean diaper. Parents can note ifthey change the baby's clothing or changed diaper types, which mayaccount for some of the weight changes. In some embodiments, additionalmeasurements may be taken as the benefit for such measurements isobserved, but with just the three measurements explained above, parentscan ascertain and track a wealth of data. Any of the three measurementscan be used as the measurement to track historically. The historicalgraph could also include two or three of these measurements on onegraph, possibly indicating the max and min ranges for baby weight atthat measurement. The difference between the first measurement and thethird measurement is an estimate of the waste contained in the dirtydiaper. The difference between the second measurement and the thirdmeasurement may be estimated as the sensor reading for a clean diaperalone, which may be useful for calculation in future measurements. Inanother embodiment, the different diapers may include a tag that quicklyidentifies the diaper type and the exact weight of the diaper used.

In one embodiment a smart diaper changing pad 100 measurement couldactually be an average across a set number of multiple measurements or arecognized plateau when a pre-determined number of measurements fallwithin an acceptable range. A measurement may also be manually recordedwhen a parent presses a measurement button. The smart diaper changingpad 100 and smart diaper app each track expected measurement ranges andalert a parent if a measurement falls outside of expected ranges.Unexpected measurement results may be excluded from the main body of agraph or chart.

The data from the smart diaper changing pad 100 can be charted andgraphed over time, including notable milestones. For example, parentscan note when a baby's first tooth came in, when a baby switched toformula or solid food, when a baby first slept through an entire night,when a baby first lifted its head, when a baby first crawled, when ababy took its first step, and when a baby spoke its first word orsentence. The smart diaper app can also note humorous or usefulstatistics such as diapers changed per day, most diapers changed in aday, which days included the most total waste product, the highestnumber of diaper changes in a single day, and the largest amount ofwaste in any single diaper. These “achievements” can be tracked acrossmultiple baby profiles or across multiple user profiles.

Pediatricians frequently request a diaper changing diary for at leastthe first month, so the smart diaper app can automatically andconveniently format such a diaper changing diary for the doctor. Thetypical columns would be diaper change time, estimate of amount in thediaper, and whether the diaper contained urine, feces, or both. Each ofthese columns may be automatically recorded or estimated by the smartdiaper changing pad 100. The smart diaper changing pad 100 can estimatethe contents of the diaper based on weight, or can use a sensor toactually read the contents (e.g., urine, feces, or both). Parents mayalso manually enter or be prompted and confirm the contents of a diaper.

Information can be tracked between multiple parents or caretakers. Eachparent can either select his or her profile when he changes a diaper orthe smart diaper changing pad 100 can recognize which parent isperforming the actions. The smart diaper app or smart diaper changingpad 100 may note which parent changed the most diapers, which parentchanged the most inconvenient diapers (e.g., late at night) or messiestdiapers, and which parent changed the most recent diaper (possiblyrecording which parent may be responsible for the next diaper change).Babies should be changed at regular intervals, sometimes as frequent asevery 3-4 hours, which sometimes necessitates multiple changes in asingle night. Tracking which parent is on diaper duty, the smart diaperchanging pad 100 can wirelessly send an electronic alert to thecurrently responsible parent when it is time to change a diaper.Additionally a microphone 127 incorporated into the smart diaperchanging pad 100 or pairing with a baby monitor (either of which ispresumably in a nursery with a baby at night) can be used to trigger thenext alert message. If a baby starts to cry in the middle of the night,an alert can be specifically sent to the on-deck parent's mobile phone,wearable, or tablet 10, waking only the parent who is currentlyresponsible to change the next diaper. Alternatively parents can pre-setwhich parent has responsibilities during which hours so that only theresponsible parent is alerted. In another embodiment both parents aresent a message, possibly indicating who should be taking the nextaction. The smart diaper app may also keep track of how long each parenttakes to respond after an alert.

The smart diaper app can gamify the diaper changing experience betweenmultiple users. Each user gains points for each diaper change,potentially gaining bonuses for the mass of the diaper change or forinconvenient times of day or taking on the diaper change duties when itisn't that user's turn or responsibility. Parents could use thegamification system to make sure that elder children are performingadequate chores around the house, and could use the gamification scoreto determine if an elder child can take a break for playing outside orplaying video games.

A parent can chart multiple children within a family against each otherto compare milestones or growth. Additionally multiple parents cancompare children or to national means or medians or other statisticallysignificant numbers (e.g., 25^(th)/75^(th) percentile or 7^(th)/93^(rd)percentile).

In another embodiment, the smart diaper app can associate digitalmemories (e.g., pictures, audio recordings, or videos of the baby orfamily) in the user's smartphone 10 or personal cloud storage with thebaby record. Because most photographs and videos taken today include aspecific timestamp, the smart diaper app or software can place thedigital memory exactly where it occurred in the baby's growth anddevelopment. Family digital memories could be simultaneously associatedwith multiple children who appear in the photograph. Users coulddirectly compare multiple profiles representing multiple differentchildren at the exact same age, even if those multiple children wereborn years apart. With permission, users could also see other babies atthe same age or same weight as their own baby for comparison. Parentswith multiple profiles for multiple children stored could look at one oftheir children's growth curves and compare directly to their otherchildren at that stage in development, either layered together on asingle graph or side-by-side. Parents can also share access to thechildren profiles with other friends and family who do not own a smartdiaper changing pad 100 so that friends, relatives, researchers, orhealth professionals can benefit from seeing the child's profile andhistory. This remote sharing can be user-specific or anonymous dependingon user preference. Additionally the remote sharing access can berestricted to a handful of known and identified users or opened up sothat everyone can see and access the information. The smart diaper appcan offer incentives (such as emoji, in-app benefits, or discounts onproducts sold through the smart diaper app or by popular retailers).Additionally users can use the smart diaper app to send invitations toother potential users that the sending user thinks would benefit fromthe smart diaper app or smart diaper changing pad 100.

Additionally parents can use the smart diaper changing pad 100 to assistin determining if a baby is eating enough. It is not possible todetermine how much a baby has breastfed directly from observation, sothe best way to detect baby consumption is to weigh a baby before andafter breast feeding. In one embodiment, the smart diaper changing pad100 incorporates a breastfeeding or feeding calculation mode. The parentcan turn on feeding mode, weigh the infant before feeding begins, andthen weigh the infant again after feeding. The smart diaper changing pad100 can determine the weight difference and even convert that to anestimated liquid volume and an estimated caloric intake. The smartdiaper changing pad 100 or smart diaper app can also track the totalweight, volume, or caloric content of all feedings over a period of timeand compare that to recommendations for that baby's age. The smartdiaper app or smart diaper changing pad 100 can also correlate thefeeding gains to the diaper change losses, showing both in one chart orgraph. If the feedings fall short of expected, pre-set, or healthyranges, the smart diaper app may suggest a visit to a pediatrician orlactation specialist. Similarly if a baby's weight or hydration fallsoutside of expected ranges, the smart diaper app may suggest a visit toa pediatrician.

Doctors and specialists can use the complete growth history, the feedinghistory, and the diaper history to get a better insight into the baby'shealth. Parents can choose to send a complete chart to their medicalprofessional to share information with a doctor without having to bringa newborn into a potentially germ-filled doctor's office. Alternativelyparents can e-mail, text, wirelessly transmit, or print and bring chartswith them for a doctor visit or specialist visit.

Additionally the aggregation of data may allow medical professionals agreater insight into newborn and baby development, allowing doctors toprovide better care to newborns and babies in the future. In oneembodiment, parents have the option to share their informationanonymously with medical professionals. In another embodiment, parentshave the option to share their baby's information with the community toimprove the representative data available through the smart diaperapplication.

One or more of the features illustrated in the figures may be rearrangedand/or combined into a single component or embodied in severalcomponents. Additional components may also be added without departingfrom the invention.

Although elements of this invention are discussed as a smart diaperchanging pad 100, the functional electronic elements could be easilyincorporated into other common nursery devices such as cribs, play mats,bassinets, baby walkers, car seats, potty training seats, and swingswithout departing from the invention. The same electronics should workin any of these form factors with only minor variations.

Additionally the same electronics could be incorporated into productsfor pets or animals. The same electronics could be easily incorporatedinto a dog mattress or a cat tree/cat scratching post to passivelycreate a pet's weight history while the pet rests. A feeding platformcould also quickly and easily incorporate the same electronics tomeasure a pet's weight and food intake each time the pet steps onto theplatform to approach the pet's food.

Instead of pets, this same feature could be incorporated into an“unwelcome mat” that is placed in front of the refrigerator, so thatevery time a user steps on the mat and looks for something to snack on,the “unwelcome mat” reminds the user of his or her weight to discourageunhealthy eating habits. The electronic elements could also beincorporated into a toilet seat so that a curious user could track thetotal weight change during a single toilet use or over a set period oftime.

It is to be understood that some terms are used interchangeably in thisdescription. As an example, changing pad, diaper pad, diaper changingpad, changing and cleaning pad, diaper changing and cleaning pad, diapercleaning pad, and cleaning pad (collectively 100) may all be usedinterchangeably in this specification while referring to the same basicstructure. Similarly any reference to a computer, computing device, ormobile device 10 should be read to inherently include a computer,tablet, mobile phone, smartphone, or wearable computer. Additionallywhile many embodiments specifically discuss an electronic scale, thesmart diaper changing pad 100 could also incorporate one or many otherfeatures without specifically incorporating an electronic scale.Additionally any action attributed to the smart diaper app can beperformed by either the smart diaper app or the smart diaper changingpad 100 and any action attributed to the smart diaper changing pad 100may be performed by the smart diaper app without departing from theinvention.
